Pot still not allowed at colleges in Wash., Colo.

While marijuana use is about to become legal in Washington and Colorado, that won't mean pot will be welcome at the states' colleges and universities.

Instead, federal laws and college rules of conduct will combine to keep pot illegal on campuses.

Darin Watkins, a spokesman for Washington State University, says most colleges have student codes of conduct that prohibit marijuana and other drugs -- and the ballot measures that legalized pot have no power over those codes.

Watkins says students at Washington State who violate the code face a variety of punishments, up to expulsion.
